Guiding access and charging optimization method suitable for electric vehicles in parking lot

Abstract

The invention discloses a guiding access method suitable for electric vehicles in a parking lot. The guiding access method comprises the following steps of: S1, establishing a traffic network adjacency matrix; S2, determining an electric vehicle parking lot selection sequence according to the traffic network adjacency matrix; and S3, determining an electric vehicle guiding access result according to the remaining vacant charging parking spaces of the parking lot and the guiding feasibility limiting conditions. The invention discloses a charging optimization method, which comprises the following steps of: S4, optimizing the charging and discharging power of a parking lot on the basis of considering standby compensation according to an electric vehicle guiding access result. According to the method, the guiding feasibility limiting condition is introduced to obtain the guiding access result of the electric vehicle parking lot, after guiding occurs, the number of the electric vehicles waiting for access corresponding to each moment of the parking lot is obviously reduced, the phenomenon of waiting for access of the parking lot is further relieved, and the actual access duration of the corresponding electric vehicles is obviously prolonged compared with the previous time; according to the guiding access result, the charging and discharging power of the parking lot is optimized, and the daily profit of a parking lot operator is guaranteed.

Description

technical field [0001] The invention relates to a guiding access and charging optimization method suitable for electric vehicles in a parking lot, and belongs to the field of charging energy management of electric vehicles. Background technique [0002] Constrained by the speed of infrastructure construction, the contradiction between electric vehicles and charging infrastructure has become increasingly prominent. After the electric car arrives at the parking lot, if there is no sufficient charging device, it can only be connected to the grid after waiting for other vehicles to leave. A large number of electric vehicles connected in disorder will aggravate the waiting situation in the parking lot, shorten the actual access time of electric vehicles, and then affect the ability of electric vehicles to participate in providing auxiliary backup. Therefore, in order to avoid this phenomenon, it is necessary to formulate a comprehensive guidance strategy and operation mode for t...

AI Technical Summary

Problems solved by technology

There are limitations in the traditional electric vehicle charging guidance method, such as: while establishing the electric vehicle guidance mechanism, it focuses on the interior of a single parking lot, and does not consider the feasibility of guidance between different parking lots

Usually, the goal of maximizing the parking lot operation is pursued, and the proposed access discrimination mechanism is not easily accepted by users.

When studying the participation of electric vehicles in providing backup, the lack of consideration for the limitation of the number of charging facilities affects the accuracy of the model
